Electrical Characteristics Limits in standard type are for T_J = 25°C only; limits in boldface type apply over the
junction temperature (T_J) range of -40°C to 125°C. Minimum and Maximum limits are guaranteed through test, design, or statistical
correlation. Typical values represent the most likely parametric norm at T_J = 25°C, and are provided for reference purposes only.
V_IN = 5V, unless otherwise indicated under the Conditions column.
